This video shows how the energy mix for the G20 has changed over the years

Over the last 50 years, the energy mix of G20 countries has changed drastically in some ways.

With many countries and regions pledging to move away from fossil fuels and towards cleaner sources of energy, the overall energy mix is becoming more diversified. But shutting down plants and replacing them with new sources takes time, and most countries are still incredibly reliant on fossil fuels.

This video from James Eagle uses data from BP’s Statistical Review of World Energy to examine how the energy mix of G20 members has changed from 1965 to 2019.

At first, there was oil and coal.

From the 1960s to the 1980s, energy consumption in the G20 countries relied almost entirely on these two fossil fuels. They were the cheapest and most efficient sources of energy for most, though some countries also used a lot of natural gas, like the United States, Mexico, and Russia.

But the use of oil for energy started to decrease, beginning most notably in the 1980s. Rocketing oil prices forced many utilities to turn to coal and natural gas (which were becoming cheaper), while others in countries like France, Japan, and the U.S. embraced the rise of nuclear power.

This is most notable in countries with high historic oil consumption, like Argentina and Indonesia. In 1965, these three countries relied on oil for more than 83% of energy, but by 1999, oil made up just 55% of Indonesia’s energy mix and 36% of Argentina’s.

Even Saudi Arabia, the world’s largest oil exporter, began to utilize oil less. By 1999, oil was used for 65% of energy in the country, down from a 1965 high of 97%.

The conversation around energy changed in the 21st century. Before, countries were focused primarily on efficiency and cost, but very quickly, they had to start contending with emissions.

Climate change was already on everyone’s radar. The UN Framework Convention on Climate Change was signed in 1992, and the resulting Kyoto Protocol aimed at reducing greenhouse gas emissions was signed in 1997.

But when the Kyoto Protocol went into effect in 2005, countries had very different options available to them. Some started to lean more heavily on hydroelectricity, though countries that already utilized them like Canada and Brazil had to look elsewhere. Others turned to nuclear power, but the 2011 Fukushima nuclear disaster in Japan turned many away.

This is the period of time that renewables started to pick up steam, primarily in the form of wind power at first. By 2019, the G20 members that relied on renewables the most were Brazil (16%), Germany (16%), and the UK (14%).

However, the need to reduce emissions quickly made many countries make a simpler switch: cut back on oil and coal and utilize more natural gas. Bituminous coal, one of the most commonly used in steam-electric power stations, emits 76% more CO₂ than natural gas. Diesel fuel and heating oil used in oil power plants emit 38% more CO₂ than natural gas.

As countries begin to push more strongly towards a carbon-neutral future, the energy mix of the 2020s and onward will continue to change.
